The utility model discloses a short-span strut-free greenhouse, relates to the technical field of greenhouses, and aims to solve the problems that a front slope single-layer greenhouse is poor in heat preservation capacity and the front slope double-layer greenhouse is poor in bearing strength. Comprising a horizontal framework, an outer greenhouse framework and an inner greenhouse framework, and the outer greenhouse framework is of an arched structure with one side inclining to form an arc. The rear wall heat preservation plate is installed on the greenhouse framework, the quilt rolling device support is installed on the greenhouse framework, and the foot margin cotton quilt is installed on a front slope of the greenhouse framework. The outer greenhouse framework is supported through the inner greenhouse framework, a central supporting column does not need to be arranged, the laying positions of inner and outer greenhouse films and cotton quilts can be reserved, and the space use efficiency in the greenhouse and the illumination condition for crop growth are improved. The overall bearing capacity of the greenhouse framework is guaranteed, and the risk that the greenhouse framework is damaged by overlarge snow load is avoided.

The utility model discloses a multilayer raisin drying net device with adjustable spacing, which comprises four vertical rods, and the four vertical rods are arranged in a square shape. Reinforcing rods are fixedly installed between the bottom portions of every two adjacent vertical rods. The four reinforcing rods form a square frame. A plurality of supporting rods are slidably connected between the front and rear vertical rods. A plurality of drying rods are arranged between the left and right corresponding supporting rods. The utility model relates to the technical field of raisin drying. The multilayer raisin drying net device with adjustable spacing can adjust the spacing between the layers of the drying net device and the spacing between the drying rods according to the actual drying requirements. When drying different amounts and sizes of raisins, the drying space can be freely changed to ensure good ventilation and illumination conditions, effectively avoid raisin stacking, significantly improve the drying efficiency and quality, and reduce the loss caused by improper drying.

The utility model relates to the field of building curtain walls, in particular to an environment-friendly garden building curtain wall. The green and environment-friendly garden building curtain wall comprises a supporting frame. A curtain wall is arranged on the inner side of the supporting frame, and a plurality of green plant planting grooves distributed at equal intervals are formed in one side of the curtain wall. Wherein a connecting assembly is arranged in the curtain wall, and the curtain wall and the supporting frame can be assembled or separated through the connecting assembly; adjusting assemblies are arranged at the positions, located at the two ends of each green plant planting groove, of one side of the curtain wall, and the angles of the green plant planting grooves can be adjusted through the adjusting assemblies. According to the green and environment-friendly garden building curtain wall, great convenience is brought to installation and maintenance of the curtain wall through the design of the connecting assembly, the curtain wall and the supporting frame can be assembled and separated easily and rapidly, the curtain wall can be overhauled, replaced and the like conveniently, the maintenance cost and difficulty are remarkably reduced, and the service life of the curtain wall is prolonged. And the influence of maintenance work on normal use of the building is reduced.

This utility model discloses a new energy vehicle battery fault detection platform in the field of new energy vehicle technology. It includes a testing workbench with lifting support rods fixedly connected to both sides of the top of the workbench. Lifting plates are installed at the two ends of the two lifting support rods that are close to each other.

Simultaneously, the platform is equipped with lighting and a power detector, providing good illumination and battery performance testing functions, respectively, further improving testing efficiency and accuracy. Furthermore, the platform's controller enables remote control of the motor and lighting, simplifying the operation process and reducing labor intensity. In summary, this utility model has advantages such as reasonable structure, simple operation, and high testing efficiency, and is of great significance for fault detection of new energy vehicle batteries.

This application relates to a mushroom cultivation greenhouse, comprising: a frame on which a tarpaulin is arranged, the tarpaulin and the frame being connected by bolts; two support frames are arranged opposite each other on both sides of the frame, and a cleaning mechanism is directly installed on the top of the two support frames, the cleaning mechanism including a driving component slidably disposed above the support frame and a cleaning component slidably disposed above the tarpaulin, the driving component being used to drive the cleaning component to move along the length of the frame; and multiple sets of pressing mechanisms, the multiple sets of pressing mechanisms being arranged opposite each other on both sides of the frame and at equal distances. This application, through the combined use of the cleaning mechanism and the pressing mechanism, can clean up fallen leaves, dust, bird droppings and other debris accumulated on the tarpaulin, as well as rain and snow, preventing rain, snow and debris from accumulating on the tarpaulin, and avoiding excessive stress on the top of the tarpaulin, which could cause deformation and collapse of the frame.

The application relates to a device for measuring the gap between a sizing roller and a control roller, and belongs to the field of cigarette manufacturing technology. The device comprises a light source, a camera and a host computer. The sizing roller and the control roller are arranged adjacently with a spacing gap, and the rotation shafts of the sizing roller and the control roller are parallel. The light source and the camera are arranged on at least one side of the rotation shaft in the extension direction of the rotation shaft. The camera head of the camera is arranged opposite to the spacing gap and is used for at least shooting image data of the spacing gap. The camera is connected with the host computer. The host computer is used for receiving the image data and determining the comparison result between the spacing gap and a preset gap threshold value based on the image data. The device can improve the accuracy of the measurement result of the spacing gap between the sizing roller and the control roller.
